摘要

采用路易斯酸配合溶解沉淀法制备了纳米级Y型酞菁氧钛(Y-TiOPc),讨论了路易斯酸及有机溶剂种类的筛选,考察了反溶剂的种类、转晶时间等因素对晶型和粒径大小的影响。结果表明,TiOPc原料与FeCl3可形成配合物溶解于二氯甲烷中,同时二氯甲烷又可作为晶型调节剂。反溶剂为H2O时,转晶12h得到粒径在100~600nm的Y-TiOPc。反溶剂中加入乙酸(V(H2O)/V(CH3COOH)=3∶7)后,转晶5h可以得到粒径为40nm的Y-TiOPc,其在780~800nm波长处具有宽吸收峰,可适用于激光打印机。

Abstract

Nanosized type Y titanyl phthalocyanine (Y-TiOPc) has been prepared using a precipitation method based on Lewis acid complexation-mediated solubilization. The influence of different Lewis acids and organic solvents on the solublization of TiOPc was investigated. The effects of different antisolvents and time of crystal transition on the crystal form and particle size of TiOPc were investigated. The results revealed that TiOPc could be dissolved in methylene chloride by coordination with FeCl3. Meanwhile, methylene chloride also acted as moderate crystallizing agent to form Y-TiOPc. When the antisolvent was water, it took 12h to get 100-600nm Y-TiOPc particles, while when CH3COOH was added as co-anti-solvent (V(H2O)/V(CH3COOH)=3∶7), it took 5h to obtain 40nm Y-TiOPc particles. As prepared nanosized Y-TiOPc exhibited an intense absorption at wavelengths of 780-800 nm, which indicated it could be employed in a laser printer. 
